Answer:
30 minutes
Step-by-step explanation:
Find the unit rate (time per SINGLE kilometer).
5/5=1 18.75/5=3.75
Multiply 3.75 (unit rate) by 8.
3.75 x 8=30
Answer:
y = -12
Step-by-step explanation:
You first calculate the x coordinate using the equation x =
, which in this case is
.
Then plug that x value into the equation to get the y coordinate:
4(-1)²+8(-1)-8 = -12
The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12
